nvlPnOvElvlENT INMA'OHINES FOR'MAKING WOODEN PINS.

The Schedule referred to in these Letters Patent and making parl: of thesame.'f

To `whom 'it may concern Be itknown that I, VROYAL HARLOW WATSON, of

Lapeeig in the county of Lapeer andv State' of Michand to the letters ofreference marked thereomand being a part of this specilication, -iuwhich-'- Figure-1 is a perspective view of my machine.

Figure 2 is a plan section of the end of thelever which works the fingerwhich throws the pins down into the hopper.

Figure 3 is a side elevation.

Like letters refer to like parts ineach figure.

The nature of this invention relates tothe construction of an apparatusfor the manufacture of-allkinds of wooden pins which require to bepointed previousv to being driven, such as dowel-pins, pins for thefasteningtogether of sash, doors, and blinds, and which may bc easilyemployed in making rake-teeth, and other similar articles.

The invention consists in a novel method of cutting the pius'from apiece of timber out into the propel' length; also, in a device forpointing said pins, and in a method of throwing them quickly out of theway, and in the adjustability and new arrangement of the various parts,as more fully hereinafter described.v

In the accompanying drawing- A represents atahle, which sustains ,theworking part of the'device. I

B are pillarblocks, iu which rotates the shaft C, driven by any suitablepower, and the pulley'D.

To the end of this shaft is attached a crank-wheel, E, provided with asuitable wrist-pin, tojwhich is secured, by a proper strap, the pitm'anF.

A cross-head, G, at the outer end of this pitmau, forms a connectionwith a piston or carrier, H, which has a reciprocating motion inthehollow guide I.

Upon'the outer end of this piston or carrier is secureda hanger, J, tothe lower end of which is' secured a hollow die, K, the boreot` whichshould be of thelcngth and diameter of' the pin,desired.y

L is a stop and guide, sccuredvto. the table,` and against it rests thetimber from which thc'pins are to he cut.

M is an arm, which is secured to the end of'the spring N, and at rightangles thereto, in such a mam' ner that the end' of the arm, which isconcave, ,will

` strike the end of the pin, which projects through the hollow die K,smartly, when the. spring is released, thereby slightly rounding orpointing vthe pin.

'lhc spring N is secured by the screws a in the jaw O, which is'adjustable, for the purpose hereinafter described, by means of the boltsb and slots e.

P .is an arm, one end of whichis securedv to the cross-head Gr', and hasa reciprocating motion there' with, while itsopposite end works in theslotted bearing Q.

To this-arm is secured `a chain or cord R, the Oppositecnd of which issecured tothe spring N.

S is another spring, secured to the table, and 'adj ustable by means ofthe screw (I and slot e. f

The top of ,this spring is two planes, incliningin opposite directions,and provided with a recess, f, inter'- posed between'the upper ends ofthe 'inclined planes.

R' is a guide, to hold/the spring N'in place.

'l is a stop, secured to the table, and adjustable by means of the`bolts g g and slots h l1..

U 'is an arm, adjustable by means of the nut i,

which passes through and'projects downward below thejarm P.

V is a lever, pivoted to the table in such a manner that it has anoscillating and vibrating compound mo- A tion. y y

The rear end of this leveris provided with a shoe,

j, with an inclined end, L'.

An arm or cam, l, is rigidly secured to and projects iromthe crank endof the' pitman, F, and, in the rotation of the crank-wheel, strikes therear end of the shoe, and depresses that end'of the lever;` then, as therotation progresses, the cam engages with the inclined end of 'the shoeandgives an outward motion to the rear end of the lever, which ispivoted at m, and whose other end has an opposite-motion to those justdescribed.

This lever is compelled to resume its original position by means of thesprings W X, to which itis connectedby rods n o.

Y isa spout. through which, and a suitable hole in the table, the pinsare delivered into any proper receptacleunder the table, while anothersuitable hole through the table allows the chips to drop Vto the floor.

The blocks 'of timber, being sa'wn to the length of the pins required,are placed upon the table against the stop L at p', and pushed up untilthe endis brought opposite the hollow die, which, then, by aforwardmotion, cuts out the pin. j

' In the continued forward motion of the pitman, the end'of theprojecting arm U passes up the inclined face s of the spring S anddepresses-the same, letting loose the spring N, which has been held backin the position show-n by the dotted lines.

'lhis spring forces, with aA smart blow, vthe concaved end of the arm 'Magainst the end of the pin just -out, and points the same.

The continued rotation of the crank-wheel withdraws anni define the die,and also the spring N, until the latter again engages with the recess s,when the block of wood should again be presented for another cut. Thecam l is now broughtinto contact with the shoe i, depressing that endot' the le\'e1"\"',and elevating its opposite end ot' the finger I',which is secured thereto. As the hollow die again advances and cutsanother pin, the last one eut pushes the preceding one through the die,when the cam I, engages with the vinclined end kof the shoe, therebyforcing the tinger t above the piu just discharged from the die, whenthe spring X depresses the l'rout end ot't-helever, compelling thefinger to throw' the piu down through the spout. The spring \V thencompels the lever V to resume its original position, with its rear endslightly elevated, as shown in the drawine'.

Should pins ot' a longer or shorter length bercquired, thejaw O, stop T,and spring S, maybe adjusted as desired, by the means already described.

For rake-teeth, aiul other similar articles, this machine will be foundadmirably adapted, while for cutting pills for the purpose specified, itwill be found very economical, making a much het-ter and stronger pinthan can he made by hand.

messo 2 What -I claim as my invention, and desire to secure by LettersPatent, isi 1. rlhe die K, operated by means of the piston H, pitmanl1,erankwhcel1 and shaft C, in combination withthe stop L upon. thetable A, constructed, arranged, and operating substantially as and forthe purposes herein described. i

2. The arm M, operated by the spring N, in combination with the arm P,chain or cord R, adjustable stop U, and adjustable stop-spring s,constructed, arranged, and operating substantially as herein set forth.l

3. lhelever V, provided with shoe j,and actuated by the springs W' X, incombination with the short beveled cam J, projecting from the pitman,arranged and operating substantially as and for the purposes herein setforth.

4. The combination of the table A, provided with suitable openingstherein, with the hopper Y, and stop L, as described, and forthepurposes specied.
